A learning disability (LD) is any disability resulting from a primary impairment in comprehending or expressing language. Many studies have looked at atypical language processes in children - particularly those with Specific Language Impairment and Dyslexia - but few have considered to how language demands, and therefore the impact of LD, change as children or adolescents transition into the postsecondary setting where auditory language abilities are often a necessary component for success.
In this study we posited that students with LD would have a more difficult time learning information from a typical lecture format, and that contributors such as extant vocabulary, short-term verbal memory, and attention would all predict outcomes for post-lecture test performance. Participants were 34 individuals with LD and 34 individuals who were typically developing (ND). Each participant watched a 30-minute lecture. Before the lecture, a baseline-test of general topic knowledge was given. Afterwards a post-test was given regarding specific information from the lecture. Additionally, multiple standardized tests and ratings were given to each participant to look at individual differences that contributed to outcomes on the post-test. We found that LD students learned less information from the lecture than did the ND students, as measured in both recall and recognition formats. Post-test performance for all students was predicted based on vocabulary and attention. Verbal memory was an additional predictor for LD participants.
